On the importance of being pedantic (series: notes to myself)

-
Image
They say that to call someone pedantic is an insult. I'm not so sure. True, someone pedantic is obsessed with minor details, small errors, or tiny imperfections. And a pedantic is also someone who cares too much about all such things not to let you know about them, advising or correcting, disagreeing or disapproving. And yes, if you are a pedant, you are more than just occasionally pedantic. This can happen to anybody, the excessive emphasis on some narrow or boring detail being a tendency we all share when it comes to matters about which we care very much. But if you are a pedant, being pedantic is your daily stance, your intrinsic nature, your way of living. You are always, consistently, reliably, systematically pedantic, from the moment you wake up, about the exact place where the slippers should be next to your bed, all the way to the moment you go to sleep, and the exact place where the phone should be placed to recharge. If you are a true pedant, no detail is too trivial, no ...

The Loebner Prize from a judge's perspective

-
Image
This year, for the first time in its history, the Loebner Prize competition was held in England, at the University of Reading to be precise. It was organised by Kevin Warwick and Huma Shah. Independently of whether Turing might have been pleased (he was not well treated in this country, recall?), there was a satisfying sense of “coming home” of the Turing Test (henceforth TT ). Expectations were high, and they very highly advertised too. The meeting was perfectly organised. Having been invited to play the role of a judge, together with several other colleagues, including two members of the IEG , Mariarosaria Taddeo and Matteo Turilli ( here are their pictures and Rosaria's interview ) , I enjoyed the opportunity to see from close-up the machinery and the TT . It was intriguing and great fun. Because there were interviews with the BBC and other things going on, and because we were also supposed to take part in the parallel AISB Symposium on the TT , I had time to test only...

Mind the app - considerations on the ethical risks of COVID-19 apps

-
[22 April update: at the Digital Ethics Lab (OII, University of Oxford) we have elaborated a list of 16 questions to check whether an app is ethically justifiable, the full article, open access, is available here ] There is a lot of talk about apps to deal with the pandemic . Some of the best solutions use the Bluetooth connection of mobile phones to determine the contact between people and therefore the probability of contagion. In theory, it may seem simple. In practice, there are several ethical problems, not only legal and  technical ones . To understand them, it is useful to distinguish between the validation and the verification of a system.  The validation of a system answers the question: "are we building the right system?". The answer is no if the app is illegal,  for example, the use of an app in the EU must comply with the GDPR; mind that this is necessary but not sufficient to make the app also ethically acceptable, see below; is unnecessar...

Between a rock and a hard place: Elon Musk's open letter and the Italian ban of Chat-GPT

-
Image
Interview by Adele Sarno for HuffPost, the Italian original is here The following English translation is provided by Google, apologies for any imprecision. Luciano Floridi, the digital philosopher, works between Oxford and Bologna, from next summer, he will leave Oxford to direct the Center for Digital Ethics at Yale. He has received the highest honour granted by the Italian Republic: Cavaliere di Gran Croce. According to the Elsevier Scopus database, he is the most cited living philosopher in the world. If today we talk about the "philosophy of information", it is thanks to him, who for 30 years, studied the connections between philosophy and the digital world. Professor Floridi, ChatGPT has been at the centre of the debate, especially these days. Elon Musk and a thousand other experts have written a letter asking for its development to be stopped for six months. In Italy, on the other hand, the privacy guarantor has decided to stop for 20 days until it complies with the pr...

(Questo testo è la Prefazione al volume: Linguaggi nella società e nella tecnica, 1968-2018 - Atti della giornata di studi organizzata dall’Associazione Archivio Storico Olivetti, in occasione del centenario della nascita del fondatore Camillo Olivetti, per riprendere e attualizzare i temi del convegno internazionale sui “linguaggi nella società e nella tecnica” promosso e organizzato nel 1968 dalla Società Olivetti. Milano, Fondazione Giangiacomo Feltrinelli, 15 Ottobre 2018). * * * Nel 1988, grazie a una borsa di studio dell’Università di Roma La Sapienza, fui ammesso come visiting student all’Università di Warwick, per studiare con Susan Haack, una delle più famose docenti di filosofia della logica. Tra i tanti ricordi, c’è quello di giornate senza fine, passate tra la caffetteria e i laboratori del campus, dormendo poco e lavorando senza sosta, scrivendo la tesi di laurea e facendo girare programmi di logica su uno dei tantissimi Olivetti M24, sempre disponibili, ad ogni ora e in...

Review of Information A Very Short Introduction

-
Information: A Very Short Introduction (Very Short Introductions) (Paperback) Review, by Lee J. Whittington Sat in a small office for a seminar on modal logic, my then logic tutor told me that "if you read something once and do not understand, it is your fault. If you read something twice and do not understand, it is the authors fault". This is something to be kept in mind when reading this book. The title should not fool the reader. This is not "Information for Dummies". The book can be technical and difficult requiring occasional reflective breaks. Unlike some of the other VSI series, to understand the book properly will take more than three or four hours. However, this is where Prof. Floridi comes into his own. Using many elegant metaphors, analogies and examples, Floridi provides some of the intuitive first steps required to understand what would be baffling concepts. My favourite metaphor is that used for understanding quantum superposition, whereby we...

(revised on Medium) On being immortal (series: notes to myself)

-
Image
I grew up with two conceptions of immortality in my mind. It took me a while to realise that they shaped my behaviours and my choices. My identity. Neither turned out to be credible. But both were useful, for they taught me a lesson. As a Catholic, I was brought up believing in a dream. I was immortal. Not backward, for I was born. But forward, because I would not die. Actually, this is not the dream, for it may be the worst of all nightmares. It is the second part that turned it into the best deal ever. I was taught, since I can remember, that if I behaved decently and repented about the rest, I was going to live a life of heavenly bliss forever, and ultimately resurrect, just the way I was (or even better), and join all the people I had ever loved and indeed billions more.  As a kid, I worried, not deeply yet frequently, about eternal damnation, the nasty side of being immortal. Speak of side effects! Better be annihilated, I calculated, than suffer horribly forever. And sometime...

Pandemic lesson: the disappearance of externalities

-
Image
Lazy neurons, they fail to see connections even when they are obvious. I cannot recall when I started hearing people talking about the global village , globalisation , hyperconnectivity , spaceship earth , Gaia , ... I grew up with this holistic language as my conceptual koiné . But only recently, thanks to the pandemic, I realised that I should have linked it to another phenomenon: the disappearance of externalities . It is so obvious now. In pseudo-precise literature or pretentious conversations, an externality is a negative effect of a profitable activity, call it a cost, paid by someone else. Like what happens if one runs a profitable business that pollutes someone else's environment.  My externalities may be unintended, possibly avoidable, but it is not my problem whether they occur, and the fact that they may occur is not going to stop me from pursuing my activities, since the cost paid by someone else is not a sufficient disincentive to sacrifice my own benefit. ...

On the need to be exposed and the beginning of philosophy (series: notes to myself)

-
Image
To be exposed.  To perceive something in such a way as to be affected, painfully, by what is imposing itself on one’s own perception, because of its barely bearable presence or absence.  The boundless blue of space and time, beyond the dark trees, in a lately lightful evening.  The unlimited blackness of nothingness, harmless, beyond your exiled existence.  The endless green intricacies of malleable meanings, latching onto each other, beyond themselves.  The bottomless whiteness of hollow horrors we inflict upon ourselves, beyond understanding.  Being exposed to all this and more precedes wonder ( thaumazein ). And protecting oneself from this exposure prevents wonder.  The mind does not bear too much exposure.  There is a reason why we prefer to linger in the darkness.  The cave is refreshing .  We do not wish to be blinded by the light outside, skin burning under the sun.  Still, a life unexposed cannot be a life lived philosophic...
